Minnesota’s Next Generation Energy Act (NGEA) of 2007—a law that restricts carbon dioxide emissions produced by power generators who export electricity to the state—violates the Commerce Clause in the U.S. Constitution and interferes with North Dakota’s energy production, North Dakota argued in a lawsuit filed against Minnesota last week.

Black Hills Corp. will build and begin operating a natural gas–fired power plant in Wyoming and shutter three aging coal plants in the state by 2014 as part of a “future compliance” plan to meet growing power demand as federal environmental rules go into effect.

Several environmental groups have asked a federal appeals court to review the Environmental Protection Agency’s (EPA) decision to grant a Clean Air Act Prevention of Significant Deterioration (PSD) permit to the 600-MW gas-fired Avenal Energy Project proposed for construction in California’s San Joaquin Valley. The groups contend that the agency exempted the project from several key air pollution standards.

Without a bold change of policy direction, the world will lock itself into an insecure, inefficient, and high-carbon energy system, the International Energy Agency (IEA) warned as it launched the 2011 edition of the World Energy Outlook (WEO) today in London.

The Nuclear Regulatory Commission (NRC) on Tuesday certified an amended version of the Advanced Boiling Water Reactor (ABWR), the third-generation reactor design offered separately by GE-Hitachi and Toshiba, which has been chosen for new nuclear builds at the South Texas Project (STP) site. The NRC’s decision means that nuclear developers in the U.S. can use the reactor in proposed projects.

GenOn’s coal-fired 400-MW Portland Generating Station in Pennsylvania’s Northampton County must significantly cut its sulfur dioxide (SO2) emissions with three years because they are adversely impacting air quality in Warren, Sussex, Morris, and Hunterdon counties in New Jersey, the U.S. Environmental Protection Agency (EPA) ruled on Monday as it granted its first-ever single source petition.

A fire that ignited in three of four steel coal bunkers at the 503-MW John Twitty Energy Center in Springfield, Mo., has sent three City Utilities (CU) of Springfield employees to the hospital for carbon monoxide poisoning. Investigation into what caused the fires is ongoing.

Fresh concerns surfaced for Tokyo Electric Power Co. (TEPCO), the embattled owner of tsunami-hit Fukushima power plant, on Tuesday. TEPCO, which is struggling to bring reactors at the plant to cold shutdown by the end of the year, detected substances from a nuclide analysis of gas emitted from Daiichi 2 that showed a fission reaction had occurred.

The collapse of a retaining bluff near We Energies’ coal-fired Oak Creek Power Plant on Monday morning sent debris, dredging equipment, and parts of a ravine filled with coal ash more than 50 years ago spewing into Lake Michigan.

Social media are transforming the world around us, and not just the world of our family and friends. Understanding how the new tools of social interaction impact the job is part of the role of today’s effective manager.

Water has long been energy production’s silent partner. In the past, we Americans seemed to take it for granted that plentiful water supplies would be available for a variety of energy needs ranging from the operations of coal-fired power plants to natural gas production activities.

TVA completed the $1.9 billion restart of the 1,100-MW Browns Ferry Unit 1 in 2007. That restart project provided the opportunity to incorporate state-of-the-art materials and radiation-reduction techniques to ensure that Unit 1 would be an industry-leading low-ALARA-exposure plant when it returned to service. The reductions achieved were significant.

Have you seen too many eyes-glazed-over expressions betraying a lack of interest at your employee meetings? Getting folks to pay attention at meetings is important, and there are ways to make it happen.

The global nuclear industry is moving forward at a brisk pace, only slightly slowed by the Fukushima Daiichi accident. The International Atomic Energy Agency’s most realistic estimate is that 90 new nuclear plants will enter service by 2030. Ten new nuclear plants went online over the past two years. We profile four of them as POWER’s nuclear Top Plants for 2011.

In our September article about the global profusion of natural gas, we based a portion of our discussion on the latest, vastly increased natural gas reserve estimates reported by the U.S. Energy Information Administration (EIA). Since our article was published, the EIA has adjusted its estimates downward. We want you to be aware of those lower recoverable reserve estimates. We also want you to know that the conclusions reached in that article do not change with the new estimates of natural gas reserves.

In many quarters, nuclear power generates enthusiasm. A single pound of reactor-grade uranium oxide produces as much electricity as 16,000-plus pounds of coal—enough to meet the needs of the average U.S. household for more than one year. And whereas burning coal emits carbon dioxide, sulfur dioxide, and nitrogen oxides, nuclear power generation is virtually emissions […]

Selecting the most economical tube for a new condenser, or the retrofit of an existing one, is much more complex than mere price shopping. Each material has unique performance characteristics that affect the operating economics of the entire plant. A case study illustrates the importance of carefully choosing the tube material that is right for your plant.

The power generation industry is a highly competitive one in which players continue to change and the race for profits is a tough one with the challenge of heavy environmental regulations. One of the most overlooked areas for cost savings is safety. Notwithstanding the moral and legal responsibilities that power plant management has for creating a workplace where everyone can work without injury, reducing and eliminating workplace injuries and illnesses is good for business.

The Office of the Inspector General (OIG) of the U.S. Environmental Protection Agency (EPA) recently concluded that the agency failed to follow prescribed policies in its peer review of the technical support document that provided the justification for its 2009 “endangerment finding” on greenhouse gases. The OIG report is timely, but in an unexpected way.

A large swath of Southern California, parts of Arizona, and Northern Baja Mexico was blacked out on Sept. 8—leaving seven million people in the dark—after an Arizona utility worker fixing faulty equipment near Yuma reportedly tripped the 500-kV North Gila–Imperial Valley transmission line, causing the outage. The blackout prompted two units at the San Onofre Nuclear Generating Station to go offline, stranded many people in elevators and trains, shut down airports, cut air conditioning on a day well above 90F, and caused damages of $97 million to $118 million, according to early estimates from the National University System’s Institute for Policy Research.

An intellectual property battle between Massachusetts-based American Superconductor Corp. (AMSC) and China’s giant wind turbine maker Sinovel in late September culminated with an Austrian court conviction of a former AMSC employee, who was arrested in Austria and who pled guilty to corporate espionage charges. The court charged Dejan Karabasevic, a 38-year-old Serbian engineer, with stealing AMSC’s software, modifying it, and secretly selling it to Sinovel.

The number of companies pulling out of the nuclear business continues to grow. Just weeks after Louisiana-based engineering firm The Shaw Group announced it would sell its 20% stake in the nuclear company Westinghouse back to partner Toshiba, German engineering conglomerate Siemens said that, prompted by the German government’s decision to phase out nuclear power by 2022, it would quit the nuclear business.

A German finance court in September questioned the constitutionality of a controversial tax on fuel used in nuclear power plants, a decision that could influence rulings in various finance courts around the country that are reviewing complaints by nuclear operators regarding the levy.
